The answer is C) selective breeding. This means that humans are deciding what to breed which means this is not a natural selection, but rather an artificial selection.
In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by Bisphosphoglycerate (BPG)
- Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), aids in the transition of hemoglobin from a high-oxygen-affinity to a low-oxygen-affinity state.
- 2,3-BPG binds to hemoglobin, causing oxygen to be unloaded. Furthermore, 2,3-BPG reduces hemoglobin's affinity for oxygen. As hemoglobin is unloaded in our tissues, 2,3-BPG binds to it, promoting oxygen unloading.
- When we increase the concentration of 2,3-BPG in our blood, the oxygen binding curve shifts to the right. This means hemoglobin will have a lower affinity for oxygen and will be able to deliver more oxygen to our body's tissues and cells.

This is because food with high content of saturated day and cholesterol can cause different diseases, and to promote that the food is healthy, food advertisers state that their food is non-fat and cholesterol-free.
A common disease is caused because of the high intake of fatty food and food that has high levels of cholesterol, is Coronary Heart Disease (CHD). It is where the coronary artery is blocked by fatty plaques or blood clots. In this way, blood flow to the heart muscles is decreased or even cut off. This may lead to the damage of the cells and eventually the heart may not function.
